In operation the two mould blocks 8 are brought together into abutment and the opposing mould sections 1 are closed up to their casting positions as shown clearly in Figure 2. This moving of the mould sections into and out of position can be effected by any suitable mechanism and in the example shown eccentrics 13, mounted on spindles 14 carried in brackets 15, mounted on each side of the backs of the mould blocks 8, are employed. These eccentrics o o-operatie with bridges 16 carried on the back of the mould sections and it will be seen that if the eccentries are rotated in one direction, by means of' the handle 17 the mould sections will be forced into casting position, as shown, which, after the casting has been effected, rotation of the eccentrics in the reverse direction will withdraw the sections from the cast plate so that. when the mould blocks 8 are moved away from each other the cast plate can be readily removed. The arrangement can be such that the mould sections 1 can be withdrawn separately or they can be withdrawn in groups but., in any event, it will be seen that they are necessarily withdrawn as independent seotions and this has proved of primary importance. In fact, it is only by reason of this splitting up of the plate into sectionsl that the larger plates can be cast. It will be understood that the molten lead, of which the plates are made, is injected through the orifice 11 and the nozzle passage 12 under pressure and the usual air outlet provided so that the metal iiows without obstruction throughout the mould. It will also be understood that when casting large sized platesl the metal may be injected at more than one position.

The foregoing invention renders it possiblel to cast quite large Plante plates-such as are required for house lighting accumulatorsf-in a machine. The important feature of the invention being the construction 'of the mould sections and the provision of a mould made up of Sections so that although all the sections may be withdrawn simultaneousl the sections are each supportedand guided?7 in a permanent frame and each operat@` as separate units of comparatively small area.

What I claim and desireto ters Patent isz-.-

1. A mould for casting large accumulator plates, comprising oppositely disposed sides, means for holding the sides in position to form a mould, a plurality of movable sections and means for moving the sections outwardly relatively to the mould, each of the oppositely disposed sides. comprising a number of the movable sections, and the movable means of each section being independent so that any section can be removed from the casting independently of the others.,

2. A mould for casting large accumulator secure by Letplates, comprising oppositely disposed sides having on their inner faces grooves and projecting ridges to form corresponding ridges and grooves on the casting, means for holding the sides in position to form a mould, means for moving the said sides away from the casting, each side being divided into sections of which the removable means are independent of those of the other sections, so that any section can be removed from the casting independently of the others and in a direction to draw the ridges thereon directly out of the grooves of the casting without injury to the casting.

3, A mould for casting largeaccumulator plates, comprising a frame, removable oppositely disposed sides iitting in said frame, a plurality of movable sections and means for moving the sections outward relatively to the frame, each ofthe oppositely disposed sides comprising a number of the movable sections, and the movable means of each section being independent so that any section can be removed from the face of pendently of the others.,

4. A mould for casting large accumulator plates, comprising oppositely disposed sides, means for holding the sides in position to form a mould, a plurality of movable sections, a plurality of eccentrics mounted on shafts, bearings for carrying the shafts, means for rotating the shafts, means for holding the eccentrics in operative relation to the movable sections,l each of the oppositely disposed sides comprising a number of the movable sections, the bearings of the shafts being fixed on the portions of the sides beyond these sections, and each section being engaged by one of the eccentrics so that by the rotation of its shaft it can be made to remove the section from the casting independently of the other sections.

5. A mold for casting large accumulator plates, comprising oppositely disposed sides, means for holding the sides in position to form a mould, a plurality of movable sec'- tions, a plurality of eccentrics mounted on shafts, bearings for carrying the shafts, means for rotating the shafts, bridges for holding the eccentrics in operativeengagement -with the movable sections, each of the oppositely disposed sides comprising a number of the movable sections,y the bearings of the shafts being iixed on the portions of the sides beyond' these sections, and the bridges being fixed on the movable sections so that by the rotation of its shaft each eccentric can be made to remove a mould section from the casting independently of the others.

6. A mould for casting large accumulator plates, comprising oppositely disposed sides, means for holding the sides in position to form a mould, a pluralityA of movable sections, a plurality of plates of uniform depth and a plurality of distance plates, a plurality the casting indeof plate carrying blocks, and means for moving the blocks outwardly relatively to the mould, each of the oppositely disposed sides comprising a number of the movable sec- 5 tions, and each section consisting of a number of the plates of uniform depth and distance plates riveted together to form a moulding surface having grooves and projecting ridges and fixed on one of the blocks, and the lo movable means of each block being independent so that any block can be removed away from the face of the casting independently of the others.

In witness whereof I aiix my signature. 15 JOHN ALFRED FULLILOVE.
